Turkey Raises Continental Shelf Issues in the Aegean Again
September 15, 2025
Turkey is reviving its claims over the continental shelf in the Aegean Sea with the planned deployment of the research vessel Piri Reis. The surveys are set to take place near Lesbos and Chios, areas that Greece claims under its exclusive jurisdiction. Turkey argues that these regions fall within its potential continental shelf, disregarding the rights of Greek islands. This action highlights the existing gap between Greece and Turkey, even as diplomatic efforts continue. The Turkish approach is also driven by frustration over Chevron's interest in exploration in the Crete area.
